FRY'S MALTED COCOA
A Combination of FRY'S Pure Cocoa and
ALLEN & HANBURYS' Extract of Malt. THE value of Extract of Malt as a nutritive and restorative agent for delicate and exhausted constitutions is now fully acknowledged by the solution and digestion of all farinaceous foods, and is therefore a valuable remedy in those diseases which arise from an imperfect assimilation of these substances. The presence of ihe active and valuable constituents of the Malt, unimpaired and in a concentrated forza is secured in ALLEN & HANBURYS' Extract by a very careful selection of the Malt used, and the greatest attention to the temperatures at which the processes of the mashing and subsequent evaporation in vacuo are carried out.
An ordinary portion contains more of the active properties of Malt than a pint of the best ale or porter.
The combination, therefore, of ALLEN & HANBURYS' Extract of Malt with FRY'S Pure Cocoa Extract supplies to Invalids and all those possessed of weak digestive powers a delicious, refreshing, and invigorating beverage for breakfast, luncheon, or supper.
Both of its constituents being highly concentrated, the MALTED COCOA is economical in use, and possesses highly nutritive properties and on this account can be recommended with great confidence to the public.
